Problems solved by technology

As a result, interaction between the ATE and the host computer as may occur, e.g., when exchanging data, can slow down the testing process significantly.
During the time that the host computer waits, the host computer may remain idle.

Embodiment Construction

[0019]ATEs that supports multi-site testing include slots, or “sites”. A device to be tested inserts into each site, and the ATE performs tests on the device in the site. Computer programs are typically involved in the testing. The ability to test devices at multiple sites without changing code in these computer programs is referred to as “site transparency”. In more detail, site transparency refers to automatic management of sites and site data such that users have little responsibility for such tasks, and barely need consider the fact that their testing is multi-site until required to do so. If effective, users will not be continuously conscious of the site dimensionality of their programming.

[0020]FIG. 1 shows a system 10 for use in testing multiple DUTs. System 10 includes an ATE 12. ATE 12 includes a device interface board (DIB) 14, that is used to connect devices to the ATE. DIB 14 has multiple sites 16a to 16d. A DUT may be inserted into each site for testing using the ATE. A...

Abstract

A device is tested using a system that includes automatic test equipment (ATE) and a computer. At the ATE, the testing includes receiving data from the device, and processing the data to obtain processed data. At the computer, the testing includes executing a computer program while the data is being processed at the ATE, where the computer program processes an object that contains a pointer, passing the object to the ATE, and receiving the object from the ATE. The pointer in the object is replaced with the processed data.

Description

CLAIM TO PRIORITY[0001]This patent application claims priority to U.S. Provisional Application No. 60 / 676,003, filed on Apr. 29, 2005, the contents of which are hereby incorporated by reference into this application as if set forth herein in full.TECHNICAL FIELD[0002]This patent application relates generally to automatic test equipment (ATE) and, more particularly, to delaying processing of objects containing ATE test data.BACKGROUND[0003]ATE refers to an automated, usually computer-driven, approach to testing devices, such as semiconductors, electronic circuits, and printed circuit board assemblies. A device tested by ATE, such as a semiconductor device, is referred to as a device under test (DUT).[0004]A test system may include ATE and a host computer. Data from a DUT may be preliminarily processed in the ATE, and then passed to the host computer for subsequent processing. The processing that occurs in the ATE and in the host computer is typically asynchronous, meaning that there ...
